In many ways, constancy is an illusion. After all, our ancestors were immigrants, many of them moving on every few years; today we are migrants in time. Unless teachers can hold up a model of lifelong learning and adaptation, graduates are likely to find themselves trapped into obsolescence as the world changes around them. Of any stopping place in life, it is good to ask whether it will be a good place from which to go on as well as a good place to remain.

Over the course of the millennia, all these ancestors in your tree, generation upon generation, have come down to this moment in time-to give birth to you. There has never been, nor will ever be, another like you. You have been given a tremendous responsibility. You carry the hopes and dreams of all those who have gone before. Hopes and dreams for a better world. What will you do with your time on this Earth? How will you contribute to the ongoing story of humankind?

I feel very strongly that I am under the influence of things or questions which were left incomplete and unanswered by my parents and grandparents and more distant ancestors. It often seems as if there were an impersonal karma within a family which is passed on from parents to children. It has always seemed to me that I had to answer questions which fate had posed to my forefathers, and which had not yet been answered, or as if I had to complete, or perhaps continue, things which previous ages had left unfinished.
